Sora 2 Pro — imagination, rendered.

Sora 2 is OpenAI's video model, and the reason to reach for it is range: surreal scenes, stylised animation and multi-beat sequences that hold together shot to shot. King AI carries both tiers — Sora 2 Pro at 1080p and Sora 2 at 720p — with no invite code and no ChatGPT subscription.

Specs

What Sora 2 Pro actually does.

Strengths

What Sora 2 Pro does best.

OpenAI's video model — imaginative scenes and stunning world-building.

Creative range

Surreal concepts, impossible physics and visual metaphor, where a literal-minded model renders the words instead of the idea.

Twelve seconds in one take

Sora's longest single generation runs half again as long as Veo's ceiling, which is enough for a complete beat without an extend.

A draft tier at a fifth of the price

Sora 2 at 720p bills 1 credit per second against Sora 2 Pro's 5 — the same model family you will deliver on, at a fifth of the rate.

World-building

Environments with convincing depth, crowds and atmosphere rather than a subject on a backdrop.

Limits

Where Sora is the wrong pick.

No model wins every shot. These are the cases where something else in the app is the better spend.

There is no 4K tier. Sora 2 Pro tops out at 1080p, so a 4K delivery has to come from Veo 3.1 4K, Seedance 2.0 4K, or a separate upscale pass.

Only three lengths exist — 4, 8 and 12 seconds. If you want a 6-second cut you pay for 8, where Kling bills any whole second from 3 to 15.

Sora is text-to-video and image-to-video only in King AI. There is no Sora reference-to-video, first-and-last-frame or extend mode, so continuity work has to move to another family.

Head to head

Sora 2 Pro against the alternatives.

The same six columns for the models you would realistically pick instead, on the same job.

How it works

Getting the most out of Sora 2 Pro.

01

Draft on the 720p tier

Sora 2 standard costs 1 credits a second against Sora 2 Pro's 5. Explore the idea there, then re-run the winning prompt on Pro.

02

Pick 4, 8 or 12 seconds

There is nothing between them. A 12-second take costs three times a 4-second one, so choose the length the idea actually needs.

03

Describe the world, not the shot list

Sora rewards atmosphere, material and light in the prompt more than camera jargon; the camera language belongs on Hailuo.

04

Finish elsewhere

Sora has no extend or 4K path. Take the clip into the extender or the 4K upscaler when it needs to be longer or larger.

FAQ

Sora 2 Pro, answered.

How can I use Sora 2 without an invite?

Download King AI or open the Web Studio. Both Sora 2 Pro and Sora 2 are in the standard model list, billed from the same credit balance as every other model. There is no invite code, no OpenAI account and no separate Sora subscription.

What is the difference between Sora 2 and Sora 2 Pro?

Resolution and price. Sora 2 Pro outputs 1080p and costs 5 credits per second. Sora 2 outputs 720p and costs 1 credit per second. Both generate audio and both support clips of 4, 8 or 12 seconds, so the cheap tier is a real draft of the expensive one.

How much does a Sora 2 Pro video cost in King AI?

King AI bills per second. Sora 2 Pro costs 5 credits per second, so a 4-second clip is 20 credits and a 12-second clip is 60. Sora 2 at 720p costs 1 credit per second, which makes a 4-second draft 4 credits. Free daily credits let you try both.

How long can a Sora 2 clip be?

Four, eight or twelve seconds. Twelve seconds is the longest single Sora generation in King AI, and there is nothing in between the three lengths. For a longer scene, chain clips in the video extender.

Should I use Sora 2 Pro or Veo 3.1?

Sora reaches 12 seconds and is stronger on surreal and stylised material. Veo 3.1 has a native 4K tier, a wider set of modes, and stronger dialogue, but stops at 8 seconds. Run both on the same prompt in King AI and keep the winner.
